Cross Sectional Study on Estimation of Stature from foot Length in Telangana

Abstract

Height is an important factor for identification. Estimation of height from mutilated bodies has significance in medico legal investigations. Foot length is equally significant for estimating the stature like other body parts by using linear regression equation. A cross sectional study on correlation of foot length in relation to the height of an individual was conducted in the age group of 18-25 years in Telangana population during the period from 1st January 2019 to 31st December 2019. A total of 150 subjects, among which 75 male and 75 female were included in the study. Measurement of foot length has been taken as length between the heel to the tip of longest toe, measured by using Vernier caliper. All the study subjects were healthy individuals without any abnormalities. The data was statistically analyzed by using SPSS (version 25) software. The linear regression formula for estimating the height is y = a + (bx), y = dependent variable (height), a = constant, b = independent variable coefficient, x = independent variable i.e length of foot. For total population the right foot formula is y = 39.25 + (5.18 x), for left foot the formula is y = 37.08 +(5.24 x). The formula for male population for right foot is y = 64.38 +(4.22 x) and for left foot is y = 62.23 + (4.30 x). The formula for female population, right foot is y = 52.47 + (4.54x) and left foot is y = 48.18 + (7.95x). The separate formula for male and female individual gives more accurate results. Calculated stature is almost close to the height of the individual; ±5 cm difference was observed in most of the individuals. The stature as per our study is approximately 7 times more than the length of the foot.
